WHEEL.

SPECIFICATION forming part of Letters Patent N o. 692,193, dated January28, 1902.

Application led April l0, 1901.

, T cr/ZZ whom t may concern:

Be it known that I, OsBoRN CoNeELToN, a citizen of the United States,and a resident of Port Chester, New York, have invented certain new anduseful Improvements in Wheels,

of which the following is a full, clear, and er.-V

' act specification.

allowed to revolve.

My inventiorrrelates to Wheels of all kinds; and it consists,substantially, in providing a wheel having a iat tread with a groove or-channel therein and a plurality of balls retained in said groove orchannel and forming the sole flange of the wheel.

It is my object to avoid the use of the fixed or permanent flange nowprovided on wheels and supply in its stead a ball or roller guide.

Referring to the accompanying` drawings, in which like letters ofreference indicate similar parts throughout the several views, Figure lis a front view of a wheel provided centrally with ball-bearings. Fig. 2is a similarview with the bearings at the side of the wheels periphery.VFig. 3 represents a double-track wheel with central bearings restingupon the track; and Fig. et is a single track, having a wheel with sidebearings thereupon.

In the form shown in Fig. l of the drawings, A is the periphery of awheel having a depression B at or aboutits central part. C representsthe balls which form the roller-bearing and which rest in the depressionB. The balls C are held in the groove snugly, but are The edges D of thegroove or depression B are extended inwardly toward each other a shortdistance, just sufli- Serial No. 55 .119. (No model.)

cient to hold the balls C in place without interfering with their freemovement and covering as little of their surface as possible.

The form of my invention shown in Fig. 2 is the same in principle asthat in Fig. l, the only dierence being that the ball-bearings aredisposed at the side of the rim of the wheel instead of the middle part.In Fig. 2 A is the periphery of the wheel, anged at E. The iiange Eextends over the balls C, which are held in the groove B by said flange.Similarly as in Fig. l, as little of the bearingsurface of the balls Cas possible is covered by the flange E. v

I have found my invention to be of advantage and practical utility inall connections where Wheels are used, but of particular importance whenused in connection with elevated cars-z'. e., in cars where the tracksare laid on elevated or overhead trestlework.

Having now described my invention, what I claim, and desire to secure byLettersPatent, is-

A car-wheel having a at tread with a groove or channel therein, and aplurality of balls retained in said groove or channel and forming thesole flange of the wheel, substantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
